Abstract:
     This "magnetic iron tester" is an instrument to electronically detect the content of magnetic iron in iron ore based on the principle that putting ferromagnetic ore in a hollow coil can increase the inductance value and the increment of inductance is in a nearly direct proportion to the content of iron in ferromagnetic ore. This test is conducted by use of test oscillator and existing technique. This test method has advantage over physical phase method in correctness and accuracy (increased by an order of magnitude) and speed (only 2 minutes).
